Without computers, in the 17th century, we could classify the entire animal kingdom... there was this idea of the speciation, right? And now, all a search engine is is essentially the mathematical speciation of ideas - and these things really derive from the way that language is used and the way words relate.
Metaphors, similes, puns - all manner of metonymy - I'm interested in language that cannot be parsed by a machine - language that can only be understood through acculturation.
